OSB 11.1.1.4 install error: Specified oepe location is not a valid location

I'm re-installing SOA suite 11.1.1.4.

The OSB I have is 11.1.1.4. (ofm_osb_generic_11.1.1.4.0_disk1_1of1.zip)

While installing OSB I encountered this "specified oepe location is not a valid location". However, the location I point to is the matching version 11.1.1.4 OEPE (oepe-galileo-all-in-one-11.1.1.4.0.201001281326-win32).

After struggling for a long time, I downloaded oepe-helios-all-in-one-11.1.1.6.1.201010012100-win32.zip, that did the trick.

I am not sure you see the irony, the matching verion OEPE doesn't work with OSB. I had to use a higher version OEPE 11.1.1.6. oh, well :-(
